[0014] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting a cleaning component, the storage box can be driven to slide by the gravity of rainwater, driving the brush to rotate, so as to realize automatic cleaning of the surface of the billboard, without frequent manual wiping, saving manpower and time costs, improving cleaning efficiency, ensuring that the billboard is always kept clean, the publicity content is clearly visible, and the publicity effect is improved. In addition, rainwater is used as a cleaning resource, avoiding the use of cleaning chemicals, reducing pollution to the environment, and complying with the concept of green environmental protection. At the same time, with the help of natural rainwater, the dependence on external water sources is reduced, water resources are saved, and sustainable use of energy is achieved. By setting up the collection and processing components, the brush can effectively avoid the splashing of sewage when cleaning through the baffle, keeping the surrounding environment of the billboard clean and tidy, reducing the pollution to the surrounding environment. At the same time, the baffle is in contact with the surface of the billboard, which can scrape off the cleaned sewage in time, reduce the phenomenon of sewage hanging on the wall, so that the billboard always maintains a clean and tidy appearance, and improves the cleaning effect; The spiral structure can effectively reduce the blockage of stains in the collection box and the transmission channel, ensure that the stains can move smoothly, improve the discharge efficiency of the stains in the collection box, and ensure that the sewage generated during the cleaning of the billboard is treated in a timely and effective manner; The cooperation of the second rack, the second gear and the one-way bearing realizes the unidirectionality and stability of the sewage transmission process.

[0031] As shown in the figure, in order to clearly implement the structure of the embodiment of the present invention, specific structures and devices are marked in the figure, but this is only for illustrative purposes and is not intended to limit the present invention to the specific structure, device and environment. According to specific needs, ordinary technicians in this field can adjust or modify these devices and environments, and the adjustments or modifications made are still included in the scope of the attached claims. DETAILED DESCRIPTION

[0032] The following is a detailed description of a self-cleaning student ideological education propaganda column provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternatives to implement some known technologies; and the accompanying drawings are only for a more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0033] like Figures 1 to 3 As shown, an embodiment of the present invention provides a self-cleaning student ideological education propaganda column, including a column 1, a propaganda column 2 is fixedly arranged on the inner wall of the column 1, a ceiling 3 is fixedly arranged on the top of the column 1, and an anchor bolt 8 with adjustable height is arranged at the bottom of the column 1. By adjusting the height of the anchor bolt 8, the propaganda column 2 can adapt to the flatness of different installation grounds to ensure the overall stability and verticality of the propaganda column 2, wherein a cleaning component 4 for automatically cleaning the surface of the propaganda column 2 is installed on one side of the column 1.

[0034] like Figures 1 to 3 As shown, specifically, the cleaning component 4 includes a storage box 401, which has the function of collecting rainwater. In practical applications, rainwater is a cleaning resource. Cleaning the billboard 2 by collecting rainwater is not only environmentally friendly but also low-cost. The storage box 401 is slidably installed on one side of the column 1. This installation method allows the storage box 401 to move within a certain range.

[0035] like Figures 1 to 3 As shown, further, a first hollow groove 402 is opened on the inner wall of the column 1, a sliding rod 403 is fixedly provided on the inner wall of the first hollow groove 402, and a first spring 404 is sleeved on the outer wall of the sliding rod 403. One end of the first spring 404 is fixed to the inner wall of the first hollow groove 402, and a sliding member 405 is slidably provided on the outer wall of the sliding rod 403. The sliding member 405 is fixedly connected to the storage box 401. At the same time, the other end of the first spring 404 is fixed to the bottom of the sliding member 405. When the storage box 401 moves downward under the action of external force, the first spring 404 will be compressed to store elastic potential energy. When the external force disappears, the first spring 404 will release the elastic potential energy to push the sliding member 405 and the storage box 401 to reset upward.

[0036] like Figures 1 to 13 As shown, in addition, a slide groove 406 is provided on the side of the column 1 close to the storage box 401, and a second spring 407 is fixedly provided on the inner wall of the slide groove 406. A limiting member 408 is fixedly provided at one end of the second spring 407, and the limiting member 408 is slidably matched with the inner wall of the slide groove 406. A limiting groove 409 is provided on the side of the storage box 401 close to the limiting member 408, and the limiting member 408 is plugged into the limiting groove 409, so that the storage box 401 can be locked when it is moved to a specific position. There is a fixed plate 410, on which a first rotating rod 411 is rotatably arranged, a sleeve 412 is fixedly arranged on the outer wall of the first rotating rod 411, and a plurality of brushes 413 are fixedly arranged on the outer wall of the sleeve 412. These brushes 413 are components that directly contact the surface of the billboard 2 for cleaning, and the bristles of the brush 413 are made of flexible and wear-resistant material, which is nylon fiber. When cleaning the surface of the billboard 2, the nylon fiber bristles can not only ensure a good cleaning effect, but also avoid scratching and damage to the surface of the billboard 2.

[0037] like Figures 1 to 6As shown, in order to realize the automatic rotation cleaning of the brush 413, a first rack 414 is fixedly provided on one side of a column 1 close to the fixed plate 410, and a first large gear 415 and a second large gear 416 are rotatably provided on one side of the fixed plate 410 close to the first rack 414, the first large gear 415 is meshed with the second large gear 416, the first large gear 415 is meshed with the first rack 414, and a first gear 417 is fixedly provided on the outer wall of the first rotating rod 411, and the first gear 417 is meshed with the second large gear 416. The second large gear 416 is meshed and connected. When the storage box 401 moves up and down on the column 1, it will drive the fixed plate 410 and the first rotating rod 411 to move. Since the first large gear 415 is meshed with the first rack 414, the first large gear 415 rotates with the second large gear 416, and the second large gear 416 rotates with the first gear 417, so that the first rotating rod 411 will rotate during the movement, thereby driving the sleeve 412 and the brush 413 to rotate, thereby realizing automatic cleaning of the surface of the billboard 2.

[0038] like Figures 1 to 8 As shown, in order to better collect and utilize rainwater, a water tank 501 is provided on the inner wall of the ceiling 3, and the water tank 501 is used to store rainwater. A filter screen 502 is fixedly provided on the surface of the ceiling 3, and the filter screen 502 can effectively filter impurities in the rainwater, prevent larger leaves, debris, etc. from entering the water tank 501, and ensure the cleanliness of the rainwater in the water tank 501. A plurality of drainage holes 503 are provided on the inner wall of the water tank 501, and a top plate 504 is fixedly provided on the surface of the fixed plate 410. Inclined plates are fixedly provided on both sides of the top plate 504. The inclination can guide the rainwater flowing out of the drainage hole 503 to flow to the storage box 401 or the brush 413, thereby improving the utilization rate of rainwater. The inner wall of the water tank 501 is inclined from one end close to the storage box 401 to the end close to the drainage hole 503. One end of the water hole 503 is gradually inclined so that rainwater in the water storage tank 501 can flow smoothly to the drainage hole 503. A plug rod 505 is fixedly provided on the side of the top plate 504 close to the drainage hole 503, and the plug rod 505 is plugged into the drainage hole 503. An inclined member 506 is fixedly provided on the inner wall of the storage box 401. A sliding groove 507 is provided on the inner wall of the ceiling 3. A return spring 508 is fixedly provided on the inner wall of the sliding groove 507. A sliding plate 509 is fixedly provided on one end of the return spring 508. The sliding plate 509 contacts the inclined member 506. The surface of the filter screen 502 is gradually inclined from the end close to the cleaning brush to the end close to the storage box 401, so that rainwater can flow smoothly from the cleaning brush side to the storage box 401 side.

[0039] When the amount of rainwater collected in the storage box 401 reaches a certain amount, the weight of the rainwater will cause the storage box 401 to slide downward. During the sliding of the storage box 401, due to the gravity of the rainwater, the limit groove 409 on the storage box 401 will squeeze the limit member 408, thereby squeezing the limit member 408 out of the limit groove 409 and compressing the second spring 407 to retract the limit member 408 to the inner wall of the slide groove 406. At this time, the storage box 401 will continue to slide downward under the action of the weight of the rainwater. When the outer wall of the storage box 401 no longer conflicts with the limit member 408, the second spring 407 resumes its deformation and pushes the limit member 408 to pop out of the slide groove 406.

[0040] When the storage box 401 slides downward, the sliding member 405 fixed thereto will be driven to move downward along the outer side wall of the slide rod 403. In this process, the first spring 404 will be squeezed. When the sliding member 405 slides down along the slide rod 403, it will also drive the fixing plate 410 to move downward. When the fixing plate 410 drives the first rotating rod 411 to slide downward, the first rack 414 on the column 1 will drive the first large gear 415 to rotate, and the first large gear 415 drives the second large gear 416 to rotate, and the second large gear 416 drives the first gear 417 to rotate, so that the rotation of the first rotating rod 411 drives the sleeve 412 to rotate, and the rotation of the sleeve 412 drives the brush 413 fixed on its surface to rotate. As the storage box 401 continues to descend, the sliding member 405 drives the brush 413 to rotate continuously, thereby continuously brushing the surface of the propaganda column 2 The surface is cleaned, and the first large gear 415 and the second large gear 416 are engaged and drive the first gear 417 to achieve the speed-increasing effect of the first gear 417. The speed-increasing effect allows the brush 413 to rotate at a higher speed, thereby generating greater friction and impact force on the stains on the surface of the billboard 2. For example, for some sticky and stubborn dust stains, the high-speed rotating brush 413 can more effectively scrape and brush them off, thereby improving the cleanliness of the cleaning and making the surface of the billboard 2 cleaner and tidier. After the speed of the brush 413 is increased, a larger cleaning area can be covered per unit time. When the storage box 401 slides downward by the same distance, the high-speed rotating brush 413 can complete more brushing movements. Compared with the low-speed rotation, the cleaning work of the entire surface of the billboard 2 can be completed faster, saving cleaning time and improving the overall cleaning efficiency.

[0041] Secondly, during the resetting process of the storage box 401, the rotation between them can be reversed. When the storage box 401 is reset, the reverse rotation of the brush 413 can make the bristles move in the opposite direction to that during cleaning. In this way, the dirt, dust and other impurities accumulated on the bristles during the cleaning process can be thrown out or shaken off in the opposite direction, avoiding these impurities from contacting the surface of the billboard 2 again during the resetting process and causing secondary pollution, thereby ensuring that the billboard 2 can remain clean after cleaning. The reverse rotation can alleviate the stress on the brush 413 during the resetting process. Since the brush 413 is subjected to the same resistance as the movement direction during the cleaning process, the reverse rotation during resetting can change the force on the brush 413, reducing the bending, deformation or breakage of the brush 413 due to continuous unidirectional force, thereby extending the service life of the brush 413. At the same time, it can also reduce the stress on the sleeve 412, the first rotating rod 411 and other components connected to the brush 413 during resetting, reduce the risk of wear and damage of these components, and maintain the stability and reliability of the entire cleaning device.

[0042] At this time, as the storage box 401 slides downward, the inclined member 506 slides downward together with it, and while the inclined member 506 slides downward, the return spring 508 of the sliding plate 509 recovers its deformation and pushes the sliding plate 509 to squeeze the inclined surface of the inclined member 506, and pushes the sliding plate 509 to slide along the sliding groove 507 in the direction of the return spring 508. When the storage box 401 slides downward with the inclined member 506 until it is no longer in contact with the sliding plate 509, the sliding plate 509 is pushed to reset by the deformation of the return spring 508, so that the sliding plate 509 does not contact the filter holes on the filter net 502, thereby opening the filter holes on the filter net 502 to collect rainwater for the water storage tank 501 in the ceiling 3.

[0043] In addition, as the sliding member 405 descends, the plug rod 505 on the top plate 504 will separate from the drainage hole 503. At this time, the water in the water storage tank 501 in the ceiling 3 will drip onto the top plate 504. Since inclined plates are provided on both sides of the top plate 504, the water droplets dripping from the drainage hole 503 will flow along the inclined plates to the brush 413. In this way, when the brush 413 rotates to clean the surface of the billboard 2, it can use rainwater to clean the billboard 2 more thoroughly.

[0044] It should be noted that when the water storage tank 501 in the ceiling 3 is full of rainwater, the rainwater can flow out through the filter net 502 and flow into the storage box 401.

[0045] like Figures 1 to 15As shown, further, in order to effectively collect and treat the sewage generated during the cleaning of the propaganda column 2, the collection and treatment component 6 includes a collection box 601, and the collection box 601 is fixedly set on the inner wall of the column 1. The inner wall of the collection box 601 is inclined. The inclined inner wall can guide the sewage to flow naturally to a specific position of the collection box 601, which is convenient for the centralized collection and subsequent treatment of the sewage. In actual applications, the sewage flows along the inclined inner wall under the action of gravity, and can more efficiently gather at the bottom of the collection box 601.

[0046] like Figures 1 to 15 As shown, the inner walls of the two columns 1 are provided with a second hollow groove 602, and a second rotating rod 603 is rotatably arranged on the inner wall of the second hollow groove 602. A spiral structure 604 is fixedly arranged on the outer wall of the second rotating rod 603. The surface of the spiral blades of the spiral structure 604 is coated with an anti-corrosion coating, and the anti-corrosion coating is an epoxy resin coating, which prevents the impurities and corrosive substances in the sewage from corroding the spiral structure 604 during the process of collecting and treating sewage, thereby extending the service life of the spiral structure 604. Its working principle is similar to that of a screw conveyor. When the second rotating rod 603 rotates, the spiral structure 604 will push the sewage to move along the direction of the second hollow groove 602, thereby transferring the sewage from the collection box 601 to the designated discharge location.

[0047] like Figures 1 to 15 As shown, a second rack 605 is fixedly provided at the bottom of a sliding member 405 away from the first rack 414, and a second gear 606 is fixedly provided at one end of the second rotating rod 603 through a one-way bearing. When the sliding member 405 slides up and down on the sliding rod 403 as the storage box 401 moves, the second rack 605 will move accordingly. Since the second gear 606 is meshed with the second rack 605, and the second rotating rod 603 is connected to the second gear 606 through a one-way bearing, when the second rack 605 moves downward, it will drive the second gear 606 to rotate, and then the second rotating rod 603 will rotate, starting the spiral structure 604 to transmit sewage; and when the second rack 605 moves upward, due to the action of the one-way bearing, the second rotating rod 603 will not rotate in the opposite direction, thereby ensuring the unidirectionality and stability of the sewage transmission process.

[0048] like Figures 1 to 15As shown, the side of the collection box 601 away from the second gear 606 is connected to the second hollow groove 602 in one of the columns 1. This connection mode allows the sewage in the collection box 601 to smoothly enter the second hollow groove 602, and then be transmitted out through the spiral structure 604. A baffle 607 is fixedly arranged at the bottom of the fixed plate 410. The baffle 607 is arranged in a semicircular arc shape, and the inner wall of the baffle 607 is equidistantly provided with a plurality of drainage holes 608. The function of the baffle 607 is to guide and control the cleaning of the propaganda column 2. The sewage generated during the cleaning process flows to the collection box 601. The semi-circular design can better fit the bottom shape of the publicity column 2, ensuring that the sewage can smoothly flow into the drainage hole 608, and the drainage holes 608 opened at equal intervals can evenly discharge the sewage into the collection box 601 to avoid the accumulation of sewage in a certain position. The size of the collection box 601 along its length direction is larger than the size of each drainage hole 608 on the baffle 607 along the corresponding direction, to ensure that the collection box 601 can effectively receive the sewage discharged from the drainage hole 608.

[0049] like Figures 1 to 10 As shown, a second hollow groove 602 connected to the collection box 601 is provided with a sewage outlet 609 on one side close to the storage box 401. For the discharge method of sewage, the present application provides two feasible solutions. On the one hand, the dirt discharged from the collection box 601 can be discharged into the buried pipe by connecting the buried pipe. This method is suitable for the situation where the campus already has a complete underground drainage system. The sewage can directly enter the campus sewage treatment system through the buried pipe for centralized treatment, which has the advantages of concealed discharge and does not affect the beauty of the campus environment. On the other hand, a collection device for storing stains can be set at the sewage outlet 609, and the staff will clean it regularly at regular intervals. This method is more suitable for some places with imperfect drainage systems or special requirements for sewage discharge. By regularly cleaning the collection device, it can be ensured that sewage will not overflow, and it is also convenient for the separate treatment or monitoring of sewage. The specific method to achieve sewage discharge can be selected according to the actual installation environment and needs, and the present application does not make specific restrictions on this.

[0050] When a certain amount of rainwater accumulates inside the storage box 401, the sliding member 405 is moved downward by its own weight, thereby causing the brush 413 to slide downward. During this process, the brush 413 cleans the surface of the billboard 2. When the brush 413 rotates for cleaning, thanks to the semicircular design of the baffle 607, when the rainwater dripping from the drainage hole 503 is accompanied by the rotation of the brush 413 to participate in the rotational cleaning of the billboard 2, it can effectively prevent the sewage generated by the rotation of the brush 413 from splashing everywhere, thereby reducing the splashing of sewage during the cleaning of the billboard 2 and keeping the surrounding environment clean.

[0051] When the baffle 607 blocks the sewage splashed when the brush 413 rotates for cleaning, the sewage blocked by the baffle 607 will be discharged in an orderly manner through the sewage hole 608. The sewage discharged from the sewage hole 608 will drip on the inner wall of the collection box 601. Since the inner wall of the collection box 601 is inclined, the sewage will naturally gather at a specific position of the collection box 601.

[0052] As the storage box 401 continues to descend, the brush 413 and the baffle 607 will continue to slide downward. When the brush 413 is cleaning the billboard 2, the baffle 607 always keeps in contact with the surface of the billboard 2. This contact can significantly reduce the phenomenon of sewage hanging on the wall after the surface of the billboard 2 is cleaned. The baffle 607 continues to scrape downward along the surface of the billboard 2, which can not only scrape off the residual sewage more thoroughly, so that the surface of the billboard 2 can be kept as dry and clean as possible, but also guide the sewage to flow more smoothly to the sewage discharge hole 608, thereby further improving the efficiency of sewage collection.

[0053] As the sliding member 405 continues to slide downward, the sliding member 405 with the second rack 605 moves downward synchronously. When the second rack 605 contacts the second gear 606, the two mesh with each other. The second rack 605 will drive the second gear 606 to rotate. The rotation of the second gear 606 drives the second rotating rod 603 to rotate. The second rotating rod 603 then drives the spiral structure 604 to operate. When the spiral structure 604 rotates, it will push and discharge the stains dripped from the collection box 601 and used to clean the surface of the billboard 2 toward the second hollow groove 602 away from the side of the second gear 606, thereby achieving effective removal of the stains in the collection box 601.

[0054] Through the continuous rotation of the spiral structure 604, on the one hand, the blockage of the stains generated during the cleaning of the propaganda column 2 in the collection box 601 and the transmission channel can be reduced. The blade design of the spiral structure 604 enables it to fit tightly against the inner wall of the second hollow groove 602, ensuring smooth movement of the stains; on the other hand, it is conducive to more efficient discharge of the stains in the collection box 601, whether it is by connecting the buried pipe to discharge the stains into the underground drainage system, or by setting up a collection device for storing stains and cleaning them regularly by the staff, the spiral structure 604 can ensure that the stains are smoothly discharged from the collection box 601, thereby improving the operating efficiency of the entire collection and processing component 6, so that the self-cleaning student ideological education propaganda column 2 can more effectively treat the sewage generated during the cleaning process while realizing automatic cleaning, thereby further enhancing its environmental protection performance.

[0055] like Figures 11 to 15As shown, a drain port 701 is provided on the inner wall of the storage box 401, a support plate 702 is fixedly provided on the inner wall of the storage box 401, a limiting rod 703 is fixedly provided on the inner wall of the support plate 702, a closing plate 704 is slidably provided on the outer wall of the limiting rod 703, the closing plate 704 is fitted with the drain port 701, a third spring 705 is fixedly provided on the inner wall of the support plate 702, one end of the third spring 705 is fixed to the closing plate 704, and a top rod 706 is fixedly provided on the side of the collection box 601 close to the storage box 401.

[0056] When the storage box 401 drops to contact with the top rod 706 due to the accumulation of rainwater inside to a certain weight, the top rod 706 will exert an upward force on the closing plate 704, so that the closing plate 704 overcomes the elastic force of the third spring 705 and slides upward along the surface of the limiting rod 703, thereby compressing the third spring 705 and opening the drain port 701. After the drain port 701 is opened, the rainwater in the storage box 401 will flow out from the drain port 701, providing a water source for cleaning the billboard 2.

[0057] When about two-thirds of the rainwater in the storage box 401 is drained, the weight of the rainwater inside is significantly reduced. At this time, the first spring 404 begins to recover its deformation and pushes the sliding member 405 to slide upward along the outer wall of the sliding rod 403 by its own elastic force. During the upward sliding process of the storage box 401, it no longer contacts the top rod 706. The third spring 705 also recovers its deformation and pushes the closing plate 704 to slide downward and reset, thereby tightly blocking the drain outlet 701 again and preparing for the next rainwater collection.

[0058] As the sliding member 405 drives the storage box 401, the brush 413 and the baffle 607 to slide upward, the brush 413 will contact the surface of the billboard 2 again and rotate to clean the billboard 2 for the second time. At the same time, the baffle 607 will be close to the surface of the billboard 2 to scrape off the wall-hanging sewage that may still exist on the surface of the billboard 2 after the first cleaning. The scraped sewage will flow into the drain hole 608 along the inner wall of the baffle 607 and finally be discharged into the collection box 601, effectively reducing the occurrence of sewage hanging on the surface of the billboard 2 and further improving the cleaning effect of the billboard 2.

[0059] As the first spring 404 continues to exert force, the sliding member 405 is driven to slide upward and reset, and the second rack 605 fixed on the sliding member 405 will come into contact with the second gear 606. When the second rack 605 moves downward, it can drive the second gear 606 to rotate, thereby driving the second rotating rod 603 and the spiral structure 604 to operate, and realize the transmission of sewage in the collection box 601; and due to the effect of the one-way bearing, when the second rack 605 drives the second gear 606 upward, the second gear 606 will not rotate accordingly, ensuring the unidirectionality and stability of the sewage transmission process.

[0060] As the sliding member 405 continues to slide upward, when the outer wall of the storage box 401 contacts the limiting member 408, the storage box 401 will push the limiting member 408 to slide to one side of the slide groove 406. This process will squeeze the second spring 407. As the sliding member 405 continues to slide upward, the outer wall of the storage box 401 will continue to squeeze the limiting member 408, so that the limiting member 408 always slides on the inner wall of the slide groove 406. When the sliding member 405 drives the storage box 401 to slide completely upward and reset, the limiting groove 409 on the storage box 401 will be precisely aligned with the limiting member 408. At this time, the limiting member 408 is no longer squeezed by the storage box 401, and the second spring 407 resumes its deformation, pushing the limiting member 408 to insert into the limiting groove 409, and again limiting the storage box 401 to ensure that the storage box 401 remains stable when not in operation.

[0061] When the sliding member 405 is fully reset, the top plate 504 connected thereto will also return to the initial position, and the plug rod 505 on the top plate 504 will be plugged into the drainage hole 503 of the water tank 501 in the ceiling 3 again. In this way, the water tank 501 in the ceiling 3 can continue to collect rainwater, providing sufficient water reserves for the next cleaning cycle of the billboard 2, so that the entire self-cleaning system can operate continuously and stably.

[0062] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
